The application calls the site a 'vacant lot'. Here's a tour of the
'vacant lot' pristine residential ocean front real estate that Facebook aims to 'de-vegetate', then perform 6 months of Horizontal Direction Drilling and lay a 10ft long vault for ther undersea cable to Japan.
When touring the lot, consider the hazards disclosed in the application:
Directional bore operations have a potential to release drilling fluids into the surface environment through frac-outs (A frac-out is the condition where drilling mud is released through fractured bedrock into the surrounding rock and sand and travels toward the surface.)
